Cosmology@Home lets you volunteer your spare computer time (like when your screen saver is on) to help better understand our universe by searching for the range of theoretical models that agree with cutting-edge cosmological and particle physics data.
FEATURED CONCEPT: Dark Matter
Unlike ordinary matter, dark matter does not emit or absorb light--or any other type of electromagnetic radiation. Consequently, dark matter cannot be observed directly using a telescope or any other astronomical instrument that has been developed by humans. If dark matter has these strange properties, how do we know that it exists in the first place?
Like ordinary matter, dark matter interacts gravitationally with ordinary matter and radiation. Astronomers study the distribution of dark matter through observing its gravitational effects on ordinary matter in its vicinity and through its gravitational lensing effects on background radiation. The background image shows the bullet cluster, a famous example where the visible matter does not follow the mass distribution.
Combining all the available evidence, dark matter represents about 83% of the matter content of the universe. Read more about dark matter on this web page. Let us know your questions and comments on the message board.

All tasks functioning normally
The problem affecting the camb_legacy tasks has been resolved. The server also recently received some under-the-hood upgrades which should improve performance and security.

camb_legacy tasks temporarily suspended
Hi everyone, there's something wrong with the camb_legacy tasks, possibly related to a recent upgrade. I've temporarily disabled them (no validation, no new workunits created) until I can figure out the problem. The camb_boinc2docker application is still working normally.

Website tweaks
Hi folks, I've made a few tweaks to the website theme. Hopefully this makes it a bit easier on the eye. These changes should also improve usability on mobile somewhat, although some work remains to be done. For now, please report any theme / user interface bugs you may find on this thread! Thanks!
